, 3 Claims. (Cl. 12S-153) My invention relates to adhesive pads forprotecting or treating sensitive places on the human foot, such ascorns, bunions, callouses, and chafed areas, and more. particularly topads made of stuck-together plies of fabric or other flexible materialeach having a film of adhesive-material onv its'under side.

Pads are widely used, of oval, round or other perimetral shape in whichthe superimposed layers, being simultaneously cut to identical shape,present a raw edge; the topmost ply being imperforate. the body-materialbelow that layer being cut away to afford a shielding recess. In thegenerally known type of construction, the raw edge of the pad exposes athin line of adhesive material at each plane of juncture between plies,and annoying results follow from this construction under some conditionsof use. Shoe pressure sometimes causes thestocking to adhere to theedge-exposed adhesive; especially so where the shoe is pliant and snugand the hose is sheer, as in womens wear. Also, shoe-pressure andrubbing tends to deform'the pad, crowding the upper plies out ofvertical line with the lowest ply, and even causing appreciablecreeping" between plies, furthering the surface exposure of adhesive Iand the ccntst or the stocking with it.

One of the objects of -my invention is to provide a pad constructionformed of material-layers each adhesive-coated on its under side, inwhich exposure of adhesive that might contact with the stocking issubstantially. obviated or minimized even under most provocative andsevere conditions of use. Other and further objects will becomeapparent` from the following description taken in conjunction with theaccompanying drawing wherein, for illustrative purposes, I have shown anembodiment of my invention in a multi-ply corn pad. y

In the drawing.

Figure 1 is a perspective view, the complete pad;

Fig. 2 is a perspective view ofthe same from below:

Fig. 3 is a vertical cross-section on line 3-3 of Fig. 1: and i v Fig. 4is a detail showing the ply-blanks in assembled relation..

The pad, generally indicated at 10, comprises a body structure 11 and acover structure 12. 'I'he body 11 is shown of conventional oval com-padshape, with the customary central opening 13 through its thickness toafford a protective recess from above, of

' or pockets, Suitable body thickness and bottom exposure of a film ofadhesive material may be provided for, and commonly are, by making thebody of a plurality of layers of commerciallyknown "adhesive clot thisbeing a closely woven fabric coated on its underside with a suitableadhesive film. Corn pads are usually made ,with two such body layers;larger pads for bunions, callouses, etc., with more than two. Thedrawing illustrates two such layers, 14 and 15, exposing the adhesivefilm 16 at the bottom and sticking the two layers together per adhesivefilm 17. According to my present invention I so construct the pad thatthere is no exposure of any line of adhesive material at the pad-edgewhere superimposed layers of material are stuck together. In-thespecific construction shown the top or cover-structure 12 is a layerthin enough for very ready flexibility, preferably made of woven fabricand coated throughout its underside with the adhesive-film 18, the blank19 (Fig. 4) of this material being 'made similar to the body inperimetral outline but of somewhat larger area to afford an edgingborder 20 extending uniformly beyond the body-blank. In thecompleted padthis edging is shaped down around the raw edge of the forming an edgingskirt or flange that is deep enough to extend past the lowest line ofadhesive material exposed at any joint between plies of the bodymaterial, substantially to the bottom of the completed pad.

It will be understood that the adhesive films and coatings abovereferred to are of a viscous, sticky characterwhich are sufficientlynon-drying to retain their sticky character in the pads aftermanufacture and during their period of use, as distinguished from dried'adhesives which have become non-adherent, and that the term "adhesive,employed in the claims, is intended to be limited to material of aviscous nature.

By the construction described it is insured that when the pad is placedupon the foot there is no external exposure of any adhesive to which thestocking might adhere, and it will be appreciated that even under mostsevere conditions of pressure-distortion of the 'plies of the pad,pressing them out of their normal direct super-position or tending tocreep one ply with respect to another, the edging makes it almost out ofthe question, from a practical standpoint, that any adhesive-film shouldbecome exposed to the stocking. d Additionally, the constructionenhances the sightliness of the pad by the uniform over-all texture andcolor of the top and edging, as well as the slightly rounded merging ofthe body'to adhere to the body-edge..

and preferably extending top and edge material, and minimizes thepossibility of getting any adhesive material on the :lingers in handlingthe article.

While I have described in detail a preferred embodiment oi my inventionin one specilc form, it will be understood that changes in the detailsof construction may be made in the embodiment of my invention Within thescope of the appended claims.

I claim:

1. A foot-comfort pad having a recessed body formed of a plurality ofplies of fabric each adhesive-coated on its underside and with thesuccessive plies stuck together by the interposed adhesive, and all ofsaid body plies being centrally apertured to form a shielding pocket,and a' cover ply of thin fabric adhesive-coated on its underside,covering said body and adhering thereto and having an edging extensionstuck by its adhesive-coating to the edge portions of the body andextending below the lowest plane of juncture of the body-forming plies.

2. A foot-comfort pad having a recessed body recae-7g formed of aplurality o'plies of fabric each adhesive-coated on its underside andwith the suc-- cessive plies stuck together by the interposed adhesive,and all of said body plies being centrally apertured to form a shieldingpocket; and a cover ply of thin fabric adhesive-coated on its underside, covering said body and adhering thereto and having an edgingextension stuck by its adhesive-coating to the perimetral side faceformed by the registering edges of the body plies and terminating at thebottom of the lowermost 1y. p 3. A foot comfort pad having a bodyadhesivecoated on its underside, said body being centrally apertured toform a shielding pocket, and a cover ply of thin fabric adhesive-coatedon its underside covering said body and adhering thereto and'having anedging extension stuck by its adhesive coating to the perimetral sideface of the body and terminating at the bottom of the body.
